摘要
通过热模拟压缩试验，研究了３４ＣｒＮｉ３Ｍｏ合金结构钢在温度８４０～１２００℃，变形速度０．１～８０Ｓ^（－１）变形条件下的热压缩行为。获得了３４ＣｒＮｉ３Ｍｏ钢的变形激活能及峰值流动应力（σ_ｐ）、发生动态再结晶的临界条件（包括临界因子Ｚ_ｃ和临界应变ε_ｃ）和再结晶晶粒大小（ｄ）与Ｚｅｎｅｒ－Ｈｏｌｌｏｍｏｎ因子Ｚ的关系，并给出了回归公式。
By means of hot compressive test, the hot compressive behaviors of 34CrNi3Mo steel in the temperature of 840℃ to 1200℃.strain rate from 0.1S￣(-1) to 80S￣(-1) were investigated.The deperdence of peak stress σ_p,the conditions of occurring dynamic recrystallization(which include critical parameter Z_c and critical strain εc) and recrystallization grain size d on Zener-Hollomon parameter was studied,their regressive formulas were also obtained.
